目的研究张力对成年动物扩张后动脉筋膜皮瓣血流的影响,并探讨有利于皮瓣血流的伤口闭合张力范围.方法 9～12个月龄成年小型香猪8只,在每只猪的背部两侧,对称各设计1个以胸背动脉穿支血管为蒂、面积为5 cm×20 cm的扩张后动脉筋膜皮瓣.皮瓣切开不掀起给予0 g张力,作为对照组;实验组则在皮瓣掀起后于远端逐步施加0、100、200、300、400、500、600、700、800和900 g的张力.测量不同伤口闭合张力下皮瓣的血氧饱和度值.结果在200～300 g张力范围内,皮瓣血氧饱和度值最高;小于此张力范围时,随着张力增加,皮瓣的血氧饱和度值逐渐升高;大于此张力范围时,随着张力增加,皮瓣的血氧饱和度值逐渐降低.结论 200～300 g是有利于猪扩张后动脉筋膜皮瓣血流的最佳张力范围,能充分利用皮瓣的伸展性,减少皮瓣并发症的发生率.

Objective To evaluate the effect of wound closure tension on the blood flow of the expanded pedicled fasciocutaneous flap, so as to find the best tension for the blood supply of the flap.Methods 8 piglets, aged 9-12 months, were used. On each side of pig back, a cephalicly based expanded fasciocutaneous flap was designed. The size of the flaps was 5 cm×20 cm. In the control group,the flaps were not elevated (0 g tension). In the experimental group, the flaps were treated at the end with the tension of 100, 200, 300, 400, 500, 600, 700, 800, and 900 g after elevation. The blood oxygen satureation( StO2 ) of the flaps was measured under different wound closure tension. Results The flap StO2 raised along the increase of tension until the tension reached 200-300 g. Then the flap StO2 decreased when the tension continued to increase above 200-300 g. Conclusions The tension of 200-300 g is good for the blood flow of expanded pedicled fasciocutaneous flap. So the flap flexibility can be best used and the complication can be avoided.
